Keep letting her talk! In fact let them all get as much air time, newsprint coverage, and social media attention as possible. The more they talk, the more they push independent and middle of the road Democrat voters to the sidelines; and consequently into the Republican fold.
I recently heard from a well connected DC swamp lobbyist that the Democrats are absolutely in a panic right now because their internal polling shows that the party is losing a large number of African American votes. If Pres. Trump gets 20-25% of the African American vote, then it's the end of the Democrat party as we know it today. By comparison, Pres. Trump received about 8% of the African American vote in 2016.
With unemployment at an all-time low, huge illegal immigration numbers (African Americans in general don't support illegal immigration), and economic growth at 3.2%, the African American community is waking up to MAGA.
